Abstract: A solar cell module and a method and a device for repairing the solar cell module are disclosed. The method for repairing a defective solar cell of the solar cell module includes cutting a plurality of wiring members electrically connecting the defective solar cell to a normal solar cell at a back surface of the solar cell module and forming previous wiring members of the normal solar cell, so that a cutting position of the plurality of wiring members is not seen from a front surface of the solar cell module, positioning a connection bar at the back surface of the solar cell module such that the connection bar crosses the cut previous wiring members of the normal solar cell and replaceable wiring members of a new solar cell, and electrically connecting the previous wiring members, the replaceable wiring members, and the connection bar.
